IMPROVEM EKT IN APPARATUS FOR STEAMING'LARD AND OIL-CASKS.

The Schedule referred to in these Letters Patent and making part of the same.

1'0 all whom it may concern: Be it known that LOBmsrornsn J. Ynucasox, of Brooklyn, in the county of Kings and State ofNew York, have invented a :new and useful improvement in Apparatus for Steaming Lard and Oil-Vessels; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make-and use the same, reference being bad to the accompanying drawings forming part a of this specification.

This invention relates to improvements in-apparatns for discharging steam into barrels and other vesscls containing oil and other like substances, through the bungs or other openings, as is required in oil-r efining and lard-repacking establishments, in removing the lard and oil and refining it; anda It consists in the application of nozzles or short discharging-tubes tot-he screw-threaded ends of steampipe by means of pipe Ts, plugged at one end, and fitted to screw the plugs against the ends of the steampipe, for stopping the flow of steam, and adapted for being received in the bung-holes of the barrels containing the lard to be removed, the said barrels beingplnccd'm er the nozzles.

1 The said arrangement is-much less expensive than,

the cocks now used, and is intendedas a substitute for them. Figure 1 is a sectional elevation of my improved steaming apparatus, and a part of a barrel, showing the mode of operation; Figure 2 is another sectional elevation of my improved apparatus, in the position when the steam is cut 6H; and l v Figure 3is a'plan view of the discharging end of one ofthe nozzles. ,7

'Similar letters'of reference indicate corresponding parts.

1 A represents the main. steam-supply pipe, leading from ,the boilers along under the floor or flaming for the support of the barrels or other vessels B, and provided with the lateral branches 0, one for each vessel, rising upward and terminating in horizontal-screwtlu e'aded ends 1), on which the screw-threaded and plugged T-shaped pipes E, having short dischargingnozzles F, are screwed, as shown, the ends D being fitted tdscrew against the inner faces of the plugs G,-

so as to make steam-tight joints.

The said plugs may be faced with yielding packing substances, if preferred, or with soft metal, or other will readily pack bles H, with cross-slots or other peribrations, calcu-' lated to distribute and direct the discharging-jets in the best manner, or TsI, provided with suitable discharging orifices, maybe attached.

The barrels are placed in the required position on the floor or other support near the, nozzles F, and the bangs are removed. The nozzlesare then quickly turnedon over, the screw-threaded 'end'l), so as to open the passage for the escape of they steam, to a greater or less extent, as rcquired alul held'so that, by a slight turn of the barrels, they will bereceivcd in the bung-holes, as represented in ii". 1, so that the discharging steam will come. in contact with=the con tents in all parts of the barrel, and melt it and cause it to flow out.

- The steam is not required to be under high pressure,

and the pipes do not, therefore, require as perfect and expensivecocks and valves as those commonly used, for which these make. very elfective and cheapfsub-.

stitutes. H After the barrels are faced of their contents, they are turned back to let the nozzles escape from the bung-holes, and the latter are quickly turned to screwthe ends up to the plugs G.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination, with the lateral pipes C, provided with screw-tln'eaded ends I), of the nozzles or discharging-tubes 1 and screw-threauled and plugged T-shaped pipes E, all arranged for operation, substantially as specified.

, The above specification of my invention signed by me this 24th day of February, 1870.
